AB  - Nano-lubricants offer improved tribological properties in many applications, such 
      as machines and engines. The presence of nanoparticles in the lubricating oil 
      affects its wear, friction, thermal, chemical and physical properties in many 
      ways. Titanium dioxide (TiO(2)) is a promising lubricant additive for enhanced 
      engine efficiency. This article reports the effect of 10 W-30 pure base engine 
      oil suspended TiO(2) nanoparticles. Four different volume concentrations (0.01%, 
      0.025%, 0.050% and 0.075%) of TiO(2) nanoparticles in the base lubricating oil 
      are used for the analysis. The tribological tests were performed at ambient 
      temperature as well as at 75  degrees C using a four ball tribometer. Scanning electron 
      microscope (SEM) and Alicona Inginite Focus G5 microscope were used to analyze 
      the worn surface. The results show that the surface-modified TiO(2) nanoparticles 
      can remarkably improve the load-carrying capacity, the friction reducing, and 
      anti-wear abilities of the additive oil. The diameter of the wear trace and the 
      coefficient of friction are the tribological properties analyzed for the 
      nano-lubricant prepared at different volume concentration (VC). It was found that 
      the diameter of the wear scar and the coefficient of friction increase with 
      increasing VC of TiO(2) nanoparticles in the lubricating oil. The main objective 
      of the paper is to present the recent progress and, consequently, to develop a 
      comprehensive understanding of the tribological behavior of engine oil mixed with 
      TiO(2) nanoparticles.
